screen backlight and distractions
I've read many a book on my veritable Palm 3e's good old grayscale LCD, alternatively backlit with Indiglo. While it now rests in electronic heaven, I routinely got up to two weeks of joy from a pair of AAA cells.
Although I couldn't care less for the author's attitude, I'm also a somewhat satisfied Kindle customer. Extolling the virtues of a passive reading screen to an opinionated crowd would be a completely moot point, so I'll mention another, often sidelined 'feature' of dedicated ereaders - their intentional lack of any other functionality.
While many smartphone users will argue that they can just as well use their 'precious' to read, I find having so many features at hand a huge distraction. It may be just my personal opinion, but know at least two other Kindle owners who think alike.
That said, the entire publishing and media industry should pull their collective heads out of *where the sun don't shine* and bring a reasonable offer on the table. Just how long will they continue to ignore that end users no longer perceive geographical location as the critical factor, especially when purchasing bundles of 1s and 0s.
